' 2 Claims. (01. 43-148) This invention relates to a novel nozzle whichis especially, but not necessarily, adapted to be used to advantage inconnection with a hose, conduit or equivalent line to assist one ineffectively spraying and distributing dust on plant life especially ongrowing beans.

More specifically stated, it is an object of the invention to subjectthe issuing stream of air and dust to the action of bafiie means whichlatter not only serves to cause better intermingling and l:

mixing of the dust and air to obtain an effective plant spray butactually diverts and separates the outcoming stream so that it isdivided and ejected in substantially diametrically opposite horizontalplanes whereby it may be effectively applied to the surfaces of plantsmore effectively and advantageously than heretofore possible withdusting nozzles currently known to me.

More particularly, novelty is predicated upon the adoption and use ofthe substantially U- tioned type which, in addition, has divergent andoutwardly projecting shields which tend to divert the pressured dustaway from the eyes and body of the walking or other attendant.

Other objects and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate likeparts throughout the views:

Figure 1 is a fragmentary perspective view showing a nozzle headconstructed in accordance with the principles of my invention;

Figure 2 is a horizontal section taken centrally on the line 2-2 ofFigure 1, looking in the direction of the arrows;

Figure 3 is a central vertical section on the line 33 of Figure 2; and,

Figure 4 is a cross section on the line 4-4 of Figure 2, looking in thedirection of the arrows.

Referring now to the drawings by distinguishing reference numerals andaccompanying lead lines, the delivery conduit hose or equivalent line isdenoted by the numeral 5 and is connected with a suitable source whereair under pressure carries a spray dust for plant dusting purposes.

This hose 6 may well be the discharge line from a portable bellows-typepower dusting device or from a wheel supported cart-type or othermachine. In fact, it could be a line on a horse drawn or other poweredmachine of a larger type. It will be evident therefore that I am notinterested in the part 6 except that it is the conduit to which myimproved nozzle head is connected. My nozzle head comprises a radiallyexpansible and contractable metal or equivalent sleeve I whoseoverlapping ends or edges 8 and 9 are joined and fastened around theconduit 6 by way of a clamping band ii). The clamp is provided withcustomaryears or lugs Illa and a connecting bolt II. An essential partof the distributive head is a substantially fiat metal strap or, let ussay, a strap which is bent into U-shaped form and which is denoted, in aunitary way, by the numeral [2. This has its limb portions I3 arouatelybent and conforming to and solderedor otherwise secured to theassembling sleeve 1.

The aforementioned baffie, which is defined by the bight portion isdenoted by the numeral [4. In addition to providing a bafile it alsoproduces and defines diametrically opposite discharge openings [5 andI6. With this arrangement,

and as indicated by the directional arrows in Figure 2, the outcomingstream of dust laden pressured air takes the general course of actionindicated by the arrows. That is to say, the head of the stream comesinto abrupt contact with the baffle forming bight M where it issubjected to considerable disturbance and is then shunted sidewise indiametrically opposite directions and is thus ejected into lateralbranches by way of the outlets l5 and it. The numerals I! and I8designate forwardly diverging guards or shields which have shankportions 19 suitably secured either to the sleeve or the limbs l3. Theyare shown here welded to the limbs I3. I find that these blinker-likewings provide not only eye guards or shields but function as auxiliarydeflector bafiles. The result is that it is possible, by properlymaneuvering the hose and nozzle, to direct the two streams, going indiametrically opposite directions, to best advantage on the surfaces ofthe beans or other plants being dusted. It is, of course a matter ofcommon knowledge that in all instrumentalities falling in the categoryherein under advisement different persons employ same in diverse ways.Some might be inclined to cant the openings l5 and Hi to the horizontalplane and others might be inclined to turn the nozzle around axiallyfrom the position shown in the drawings and feed it into the branches ofthe plants and shoot the streams vertically. Nevertheless the generalidea is that the pressured air propelled dust waves come through theconduit, strike the bight portion or bafiie and split into oppositestreams and are partly thrown forwardly by the diverter shields l1 and(8. It thus becomes possible to play the insecticidal dust streams inthe manner desired.

A careful consideration of the foregoing description in conjunction withthe invention as illustrated in the drawings will enable the reader toobtain a clear understanding and impression of the alleged features ofmerit and noveltysufiicient to clarify the construction of the inventionas hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts maybe resorted to in actual practice so long as no departure is made fromthe invention as claimed.

Having described the invention, what is claimed as new is:

1. A duster nozzle of the class shown and described comprising acylindrical sleeve adapted to be telescopically fitted over thedischarge end of a pressured dust delivery and discharging conduit, arelatively wide U-shaped sheet material strap having limb portions andan adjoining bight portion, said bight portion being concave-convex andconstituting a bafile, the ends of the limb portions being attached atdiametrically opposite points to said sleeve and co-acting with thedischarge end of the latter in defining a pair of discharge openingsopposed to and in alignment with each other and both at right angles tothe longitudinal axis of said'sleeve, means'for clamping said sleeve onsaid conduit, and a pair of deflectors secured to said sleeve andprojecting beyond said discharge end and disposed outwardly of and inalignment with said discharge openings, said deflectors having theirouter ends free and slanting away from said discharge openings indivergent relation in respect to each other and constituting eyeprotector shields.

2. A dust distributing and spraying head construction of the class shownand described comprising a relatively wide sheet material strap defininga U-shaped unit embodying a curved bight portion defining a bafiie andfurther embodying a pair of limbs, the end portions of said limbs beingfree and arcuately shaped, an open ended cylindrical sleeve having oneend portion fitted and secured between the arcuately shaped free endportions, the discharge end of said sleeve being spaced from saidbafile, a pair of duplicate deflectors including forwardly and outwardlydiverging shields and shank portions, the respective shank portionsbeing attached to the aforementioned limbs and sleeve, said shieldsbeing disposed outwardly of the respective co-acting longitudinal edgeportions of the limbs and said bafiie and being at approximate rightangles to said limbs.
